Question

which of the following could not be the measures of the angles of a triangle? A. 30^o - 120^o -30^o B. 40^o - 40^o - 100^o C. 60^o - 60^o - 60^o D. 70^o - 50^o - 70^o

Answer 1

D. 70^o - 50^o - 70^o

Explanation:

Answer 2

D. 70^o - 50^o - 70^o

Explanation:

The 3 angles of a triangle add to 180 degrees

A. 30^o - 120^o -30^o = 30+120+30 = 180

B. 40^o - 40^o - 100^o = 40+40+100 = 180

C. 60^o - 60^o - 60^o = 60+60+60 = 180

D. 70^o - 50^o - 70^o = 70+50+70 = 190 not a triangle
